I wrote a little installer script, based on the Python Eye-Fi server by Jeff Tchang, and a fairly extensive installation how-to, see http://thijs.elenbaas.net/2013/03/installing-an-eye-fi-server-on-a-synology-nas/. Let me know if it works for you!
In install.sh, replace PYTHONPATH=/usr/local/python/bin
PYTHONPATH=/usr/bin/ <– change here, no "python" after /
Same has to be done in /usr/local/etc/rc.d/S99EyeFiServer.sh
